Application lfiled September 19, 1922. Serial No. 589,122.

To all wlw/m, it may concern:

Be it known that I, CARL WALLDow, a citizen of the United States, and resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Sack Holders, of which the following is a specification.

It is the object of my invention to provide a device for supporting a sack in an open position for filling.

It is a further object of my invention to provide a device of the character indicated whereby a simple means is provided for holding a sack in the required position prior to positioning the hopper thereover, and whereby the saclr` may be securely fastened in position for filling by means of elements carried by the hopper itself.

It is a still further object of my invention to provide a device of the character indicated whereby the sack to be filled is securely held in an open position during the filling process, and whereby the raising of the hopper after the sack is filled automatically releases the filled sack. y v

Finally it is an object of my invention to provide aI sacker of the character indicated which is positive in its action, simple in construction, economical to manufacture, and highly efficient in its practical application.

In the drawing Figure 1 is a side elevation of my improved sacker.

Figure 2 is a rear view of a portion of the sacker.

Fi ire 3 is a cross-section through the sack olding members.

Figure 4 is a side elevation of the sack holding clamp.

Figure 5 is a plan view of the same.

Referring more particularly to the drawing, I show a suitable frame having legs 1 and top and bottom bars 2-3 respectively as shown. The rear legs 1 are extended a distance above the top bars 2 as at 4 and is cut on a bevel as at 5. Pivotally mounted upon said rear legs by means of hinges 6 is a hopper 7 constructed as shown.

Mounted upon top bars 2 and spaced apart approximately the width of a sack are spring supporting members 8 held in position by screws 9 and having projecting ears 10 formed on the outer side thereof as shown7 while passing through ears 10 are pins l1 around which the ends of a spring member 12 are coiled. The member l2 having its ends 13 projecting downwardly and being in Contact with the membersv 8, the rest of the spring being bent upwardly thence over the upper edge of` member 8 and'then curved as shown with their'inner cross portion 14C curving upwardly to form a portion under which the edge of the sack may be easily slipped. Passingth'rough the upper portion of member 8 and through the' bars2 are oricesl. v

Mounted upon the lsides of hopper 7 are sack holding members 16-17, the lower ends of which are pointed and slightly curved as f at 18. The location of said members 16-17 which engages the upper portion of member 8 and thus supports this edge of the hopper taking the strain off of the hinges 6 as is readily apparent.

The operation of my improved sa'cker is as follows,- f 1 f p,

rfhe hopper' being raised as indicated in dotted lines at 20in Figure 1 the upper edge of the sack to be filled is slipped under the portions 14 of spring members 12,`the ten-v sion of the springs holding the'same in posi tion. rThe hopper 7 lis lowered and the pointed portions 18 of the members 16-17 pass through they sack in entering their respective orifices 15 and thus effectively and positively support thesack without any danT ger from slipping. p i e The sack is now securely fastened at four spaced points with the hopper discharging directly into its open mouth.v When" the *I ysack has vbeen filled through the hopper, the

strong enough to support a filled sack until it is withdrawn by the operator, or they may be so constructed as to permit the filled sack to drop to the ground as soon as the hopper is raised. Upon the removal ofa filled sack the operation is repeated by again slipping y the edge of an empty sack under springs `12 and dropping the hopper into position.

.As the weight of ill@ hopper is mainlyoarw ried hy shoulders 19 on members 16 and the hevelled surfaces 5 of the rear legs l the hinges are put under but little strain and will last indefinitely.

lt may thus be seen that l have provided a new and novel means or holdingand re leasing a sack placed in my improved device and one which is positive in action, as well as extremely simple in form and construction, economical to manufacture and easily and quickly operated.

it is to he understood, or course, that while ll have herein shown and described the pre- 'erred embodiment oi' my invention changes in form, proportion, construction and method of operation may he made within the scope of the appended claims.

I claim l. A sacker comprising a "frame, a hopper having downwardly and inwardly inclined sides pivotally mounted thereon, spaced pins arranged on each of two oaposite sides of said hopper to assume a vertical position when the hopper is in an operative position, and meanscarried by a portion of said pins for engaging said trame to support said hopper thereon.

2. A sacker comprising a Jframe having orifices formed therein, a hopper pivotally mounted thereon, means for supporting an empty sack in an open position thereon, and means carried by said. hopper adagted to pierce said saclr and enter said orifices, said last mentioned means having shoulders rormed thereon to engage said trame and thereby support said hopper.

3. A sacher comprising a trame having oriiices formed therein, a hopper pivotally mounted thereon, resilient clips mounted on said trame to engage sack edges, and means carried hy said hopper adapted to pierce said sack at the points grasped by said clips and enter said orifices.
